New approaches in computational metallurgy
Metallic alloys are uniquely strong, ductile and recyclable, but predicting how components fail remains a grand engineering challenge, limiting performance and increasing costs/emissions.

Our research pushes the boundaries of theory and simulation for materials, connecting atomic dynamics to engineering properties. Drawing broadly from mechanics, physics, statistics and machine learning, a particular focus is quantifing uncertainty in multi-scale, data-driven models.

One recent theme is model-agnostic simulations: to quantify multi-scale uncertainty and incorporate multi-scale data, simulation outputs need to be smooth functions of model parameters, not static numbers. Whilst well known in many fields (e.g. adjoint/tangent schemes in FEM) we are developing new model-agnostic approaches for atomic material simulations, for inverse fine-tuning in back-propagation and model-form UQ in forward propagation.
Keywords: dislocations, multi-scale UQ, atomic simulation, forecasting
